Application filed October 12, 1896. 7 Serial No. 608,567. (No model.)

T0 on whom it may concern.-

' Be it known that I, BENJAMIN S. SEAMAN, a citizen of the UnitedStates, and a resident of Canton, county of Stark, State of Ohio, haveinvented a new and useful Improvement in Bicycle-Saddle Frames andHolders, of which the following is a full, clear, and exact description,reference being had to the acpart of this specification.

My invention relates to improvements in bicycle-saddle supports; and itconsists of certain features of construction, as herein- Figure 1 of thedrawings is a View in perspective of a saddle-support, illustrating myinvention. Fig. 2 is a similar view of a bindin g-staple by which thecantle is bound to the spring. Fig. 3 is a similar view of the rear endportion of the spring, the end portions of the staple shown in Fig. 2,and the bindingnut. Fig. 4 is a view partly in perspective and partly insection 2 2, Fig. 3. Fig. 5 is a perspective of the upper end portion ofthe post and a detail of devices by which the spring is secured to thepost, and Fig. 6 is a section longitudinally throughthe head of thepost.

Numeral 1 designates the post, having a T- shaped-portion 2, having inthe end portions thereof slots 3, in which are placed clamps or plungers4, that engage the spring 5, that is secured in such engagement by thenuts 6, which bind the T portions firmly upon the clamps or plungers andsecurely retain the spring in desired adjustment. The spring 5 is of theform shown, having at the rear portion side loops 7 to receive thethreaded end portions 8 of the staple 9. In the central top portion ofthe cantle 10 is provided a longitudinal recess 11, having at its endportions through apertures adapted to receive the threaded portions 8 ofthe staple 9., The threaded ends of the staple 8 pass through the loops7 of the spring 5 and are secured therein by the conical nut 12.

At the front end of the spring 5 is provided a block having thereinsockets 13 14 14, the latter two to receive the front ends of the spring5 and the former to receive the seatleather tension-screw 15. By the useof the staple form of uniting the two bolts 16 and the nut 12, having aconical under. portion adapted to the form of the loop 7 the spring isheld securely to the cantle-frame.

'One of the advantages of the staple and in the construction of thisdevice over the bolt used in other constructions is that in the lattercase it frequently happens that the nut works off the bolt and the boltis therefore liable to be lost. In my device if one of the nuts of thestaple should work off the bicycle would not be disabled, but could beused until a new nut be furnished, as there would be no liability of thestaple being disengaged from the cantle.

Having thus fully described the nature and object of my invention, whatI claim is- 1. In a'bicycle-frame, the combination with the saddle-posthaving a screw-threaded T- shaped portion formed with longitudinalslots, of the saddle-spring located in said slots, the clamps seatedinsaid slots and bearing against the spring, and .the securing-nuts,substantially as described.

2. The combination with a bicycle-saddle post, the saddle-spring of theform shown provided with loops at the rear end, and the cantle providedwith a transverse recess in its upper side, of the staple havingscrewthreaded ends passing through holes in the cantle and through theloops of the spring, and the conical nuts engaging with thescrewthreaded ends of the staple, substantially as described.

'In testimony whereof I have hereunto set my hand this 9th day'ofOctober, A. D. 1896.

BENJAMIN S. SEAMAN.
